NGC 6946  焰火星系 







NGC 7331  科德韋爾30(Caldwell 30) 






想找 NGC 7331 裡面的 超新星 SN 2025rbs   


SN 2025rbs 相當接近星系的核心,而且距離七月爆發已經相當久了,
相對不容易找到

Apple Watch 11 購買記 - - 開箱、設定、測試

  Apple Watch 11 購買記  - - 開箱、設定、測試   


購買記 

最近想買Apple Watch 11 來測量自己的心率、血氧、與心電圖,

網上幾個賣場只能登記,沒有現貨,

前幾天的傍晚,我特地第一次親自去到傳說中的Apple直營店,信義A13,到了繞了一圈,找不到店,原來是在B2, 

好大一間的Apple直營店面,看了感覺滿神奇的,

我試戴了幾款樣式、顏色,決定好要買了,

未料是「沒有貨」! 生意這麼好?賣到缺貨?

後來還是回家上Apple官網訂購,

大約一個星期後會送來…







開箱 

回家上Apple官網訂購Apple Watch 11 ,

三個工作天,Apple Watch 寄到了! 超級快的!






盒背有註明: iPhone 需要升級到 iOS26以上,才可以跟 Apple Watch 11 配對! 

感覺有點頭痛,因為怕 iPhone 需要升級到 iOS26 以後,會有不可預期的麻煩...

不過為了能使用 Apple Watch 11 配對,也只好把 iPhone 升級到 iOS26 了,

還好已經有 iOS26.0.1 了,應該會好一點。












還好我的 iPhone 14 pro Max 升級到 iOS26.0.1 之後,還滿順的,速度還比以前變快一些,

iPhone 跟 Apple Watch 11 配對還滿順利的。



 
第一次設定 Apple Watch 11 ,手錶問我一些問題...




測試  

 測試 Apple Watch 11 量的準不準呢?

製作 Allsky 全天相機 - Raspberry Pi 樹莓派 安裝 allsky 軟體,Tapo C325WB 改鏡頭

 製作 Allsky 全天相機  
  Raspberry Pi 樹莓派 安裝 allsky 軟體 
  Tapo C325WB 改鏡頭  


Raspberry Pi 樹莓派 也用了幾年了,差不多就是個小電腦,滿好用的,

適合 24小時開機,執行相對簡單而想要一直執行的程式功能。 好處是省電,又比電腦便宜。


安裝 allsky 全天相機軟體,可以拍攝 全天星空,樣子類似 星座圖 的呈現,滿漂亮的。



** 原作軟體 allsky **  


安裝軟體:


https://github.com/AllskyTeam/allsky?tab=readme-ov-file




********************************************

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install git

Installation

The following commands will put the new release of Allsky in ~/allsky. Except for some system files, all Allsky-related files reside in this directory. If you later install the Allsky Website on the Pi, its files will also go in this directory.

cd~
git clone --recursive https://github.com/AllskyTeam/allsky.git
cd allsky
./install.sh

The git clone will take a couple minutes and should produce output similar to what's below. The new allsky directory is approximately 150 MB after download.

Cloning into 'allsky'...

The installation prompts for several items that allow it to configure the Pi so Allsky runs most efficiently given your Pi's configuration. These prompts include:

  • New host name, if not the default of allsky. If you have more than one Pi on the same network they must all have unique names. For example, if you have a test Pi you may want to call it allsky-test.
  • Adding swap space if needed. Swap space effectively increases the amount of memory your Pi has. Insufficient swap space is one of the leading causes of timelapse video creations problems.
  • Putting the ~/allsky/tmp directory in memory instead of on the disk. This directory holds temporary Allsky files and is where most Allsky files are written to. Putting the directory in memory significantly reduces the number of writes to the SD card, which increases its life.
It's highly recommended to accept the defaults.



Post installation

After installation, reboot then perform any actions the installation script identified.

If instructed to copy the contents of a prior configuration file to the new release, it's important to manually copy the values from the old file to the new file and not copy the entire file.
After the reboot, do the following:

帳號,密碼:  
  1. Bring up the WebUI by entering http://allsky.local or http://allsky.localhost in a web browser. The default username is admin and the default password is secret.  
    If your website is publically viewable you should change the username and password via the Change Password link on the WebUI.
  2. Go to the Allsky Settings page.
  3. Make any necessary changes.
  4. Click on the Save changes button. Allsky will (re)start.
  5. If instructed to update the config.sh and/or the ftp-settings.sh files:
    1. Go to the Editor page.
    2. Select the appropriate file in the drop down list.
    3. Edit the file. Do NOT simply copy a previous version.
    4. Click the green "Save Changes" button. Allsky will not restart but the changes will take effect when the next image is taken.
安裝完成之後,要進入網頁的 Allsky Settings 調整各項設定:  










為了偵測流星,做了一組 Allsky 全天相機,與「北東南西」朝四個方向的一體攝影機:

** 原作軟體 indi-allsky ** ( 較新版的 allsky... )  


安裝軟體:

https://github.com/aaronwmorris/indi-allsky/wiki/Getting-Started


sudo apt-get update


sudo apt-get upgrade


To run an instance of indi-allsky, you need to perform the following actions:


  1. Install git
sudo apt-get install git


  1. Clone the indi-allsky git repository
git clone https://github.com/aaronwmorris/indi-allsky.git

  1. Navigate to the indi-allky sub-directory
cd indi-allsky/

  1. Run setup.sh to install the indi-allsky system
./setup.sh

帳號,密碼:自訂 - 需要記好!!  
( Raspberry Pi 4B 大約跑了 19分鐘 )



The setup.sh script will tell you if you are required to build the INDI software (documented below)

Note 1: If you run into problems with missing commands here, you may need to install additional packages to get started.


如果出現提示:系統還沒有安裝 INDI software, 則需輸入以下指令: 


sudo apt-get install lsb-release libc-bin whiptail

或是

./misc/build-indi.sh

( Raspberry Pi 4B 大約跑了 30分鐘 )




INDI-Allsky Software Review

https://www.gordtulloch.com/2023/01/06/indi-allsky-software-review/

Installing INDI-Allsky [2]is pretty much the same as installing the TJ software, where you open up a command line (scary I know!) and copy in the following commands:

apt-get install git
git clone https://github.com/aaronwmorris/indi-allsky.git
cd indi-allsky/
./setup.sh
systemctl –user start indiserver
systemctl –user start indi-allsky

安裝過程,前段選擇camera要正確,後段出現的選項,儘量都選「內定值」, 

這樣,差不多都會成功了! 


2024-12-28 

安裝成功了! 









2024-12-28 

安裝了四次都失敗! 

心裡想 可能需要重新安裝,或者直接 放棄 ....

第五次安裝,在安裝 indi 系統時,「進階檔案功能」等等幾個選項都不要,

沒想到 可以執行 indi-allsky 了!

但是 AWB「自動白平衡」需要手動打開,不然影像超暗,

畫面上的字超小,而且很難調整,

然後一直出現 No image ...















如果 indi-allsky 的設定 調到調不回正常,

用以下方法「恢復 內定值」


Reset Configuration

Aaron W Morris edited this page on Feb 14 · 2 revisions

Overview

Use these instructions if you want to revert all configurations to the defaults.

  1. Stop indi-allsky

     systemctl --user stop indi-allsky
     systemctl --user stop gunicorn-indi-allskyㄎActivate the virtualenv
  2. cd ~/indi-allsky
  3. source virtualenv/indi-allsky/bin/activate
  4. Backup current config

     ./config.py dump > indi_allsky_config_$(date +%Y%m%d_%H%M%S).json
    
  5. Flush all configs

     ./config.py flush
    
  6. Bootstrap a fresh config

     ./config.py bootstrap
